You might, depending upon your lifestyle and image projection, want a cosmetic tint with little change in the light input but of course that tint will remain for all circumstances in which you wear that eyeglass.

Premium IOL: Toric iols correct astigmatism . Multifocal and accommodative iols correct presbyopia. Multifocals provide better reading compared to accommodative iols but can result in a degradation in the overall quality of vision and produce side affects such as haloes around lights.
